When cloning a chunk of tracepoints, we cannot just copy the elements
of the traces[] array. We also need the payloads associated with
those.
This change introduces a new u_trace_payloaf_buf object that is
refcounted so that we can easily import traces[] elements and their
payloads from one utrace to another.
